Answer:
1) -4
2) 1/4
Step-by-step explanation:
8x + 2y = 7
-8x -8x
<u>2y</u> = <u>-8x + 7</u>
2 2
y = -4x + <u>7</u>
2
4^1 = 4
4^2 = 16
4^3 = 64

Answer:
a) 83
b) mean and mode are both 83
Step-by-step explanation:
a) mean is the average. so add all the numbers and divide by the number of numbers.
<u>88 + 73 + 81 + 83 + 79 + 94 + T</u> = 83
7
b) median - put the numbers in numerical order, smallest to largest, what is the middle number (4th number) 73, 79, 81, 83, 83, 88, 94
mode - which number shows up most frequently?
Angle measurement DEF=107 degrees
You must first find angle F- since it is against a flat line, we know 180=F+135. Subtract 135 from each side and we find F is 45 degrees.
Then, since a triangle’s angles must always equal 180 degrees, we subtract angles D and F from 180 to get 107 degrees.
Answer:
7000
Step-by-step explanation:
lets start with 695
9 is the thousand
you check the number next to 9
less then 4 let it rest
more than 5 let it soar
something like that lol
anyways since 5 is next to the 9 we round up from 9 to the next number which is 10
so that changes the whole number to 7000
hope this makes sense!
